Given numbers are 470, 644, 278, 534

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(470, 644) = 151340

GCD(470, 644) = ( 470 x 644 ) / 151340

= 470 / 644

= 470

Step2:

LCM(2, 278) = 278

GCD(2, 278) = ( 2 x 278 ) / 278

= 2 / 278

= 2

Step3:

LCM(2, 534) = 534

GCD(2, 534) = ( 2 x 534 ) / 534

= 2 / 534

= 2

So, Greatest Common Divisor of 470, 644, 278, 534 is 2
